BODY TRANSFER HOIST George E. Pentecost, Milford, Ill.

Application October 29, 1952, Serial No. 317,397

3 Claims. c1. 254-8) This invention relates to body transfer hoists, andmore particularly to hoists adapted to lift a body from one restingplace, move it into position over another resting place, and lower itonto the second resting place.

An object of this invention is to provide an improved device of thischaracter which is efficient and easy to operate and which iscomparatively inexpensive to manufacture.

Another object is to provide a device of this character having a novelsupporting base adapted to be adjusted so as to fit under varioustables, casket pedestals, and other resting places.

Another object is to provide a device of this character having a novelhydraulic lift mechanism.

Other objects will become apparent from the detailed descriptionfollowing, which refers to the appended drawings, in which:

Figure 1 is a view in elevation from in front of one embodiment of myimproved body transfer hoist, show ing in broken lines a body supportedthereby.

Figure 2 is a view in side elevation of the same hoist.

Figure 3 is a plan view of the same hoist, showing in broken lines thebase legs in their fully spread position.

Figure 4 is an enlarged fragmentary view substantially along line 44 ofFigure 1, showing a detail of the leg spreading mechanism.

Figure 5 is another enlarged fragmentary view along line 55 of Figure 4,showing another detail of the leg spreading mechanism.

Referring now to the drawings, in which like numbers refer to likeparts, one embodiment of my invention is illustrated consisting of anhydraulic body transfer hoist generally designated 19, including ahorizontal base, generally designated 20, which comprises a rigidrectangular frame, generally designated 21 at the rear of hoist 10, anda pair of horizontal legs 22 and 23 pivoted at their rear endsrespectively to vertical hinge pins 24 and 25 in the rear corners offrame 21. Legs 22 and 23 are thus pivotally mounted to the rear cornersof frame 21 for horizontal swinging movement about said rear corners,which are also the rear corners of body transfer hoist 10.

Frame 21 has side rails 27 and 28, a front rail 29, and a rear rail 31.Legs 22 and 23 are much longer than side rails 27 and 28, and extend tothe front of hoist 10, beyond the center of body support means 30, asbest seen in Figure 2.

Base 20 is supported above the floor by means of casters mounted underthe rear corners of frame 21 at 32 and 33, and under the front ends oflegs 22 and 23, at 34 and 35 respectively. Thus hoist may be moved abouton a floor.

Means is provided for spreading legs 22 and 23 apart in the mannerillustrated in broken lines in Figure 3, which will now be described. Ahorizontal shaft 36 is rotatably mounted in frame 21, with its endsextending beyond front and rear rails 29 and 31 as best seen in Figure4. A lever 37 is fixed on the rear end of shaft 36, and a transverse bar38 on the front end, extending 2,739,733 Patented Mar. 27, 1956 ICQ.

the top of mast 40 is a boom which extends approximately horizontallytoward the front of body transfer hoist 10. Boom 50 is preferably forkedas at 51, so as to terminate ina forked front or outer end 52--52, asbest seen in Figure 3. Depending from the outer or front double end ofboom 50 is a body support means 30, which may be suspended by chains 53.The structure of body support means 30 is not a part of the presentinvention. It is believed that its use with transfer hoist 10 will beapparent from the drawings, and that it is unnecessary to describe it.

Mechanism is provided for raising and lowering boom 50 which will bedescribed hereinafter. In order to obtain a substantially straight liftof body support device 30, extensions 54 are provided below the forkedend of mast 50 to hold chains 53 at substantially the same radius frompivot 47 within the range of lift of boom 50.

A shelf 55 is secured to mast 40 on which is mounted a jack 60, fromwhich extends upwardly a lifting or piston rod 61. Supported by pistonrod 61 is a sliding member 70 comprising a vertical member 71 to whichare secured,

as by welding, a pair of collars 72 and 73. These collars are slippedover the top of mast 40 in assembly (before stay 44 is attached) andhave a freely sliding fit with mast 40. A lug 74 welded to one of thesaid collars provides a pivot 75 for the lower end of a connecting rod76 the upper end of which is pivotally connected at 77 to boom 50intermediate its ends. Pivot 77 is placed relatively close to pivot 47as best seen in Figure 2, so as to multiply the throw of the front orouter end 52 when jack is operated.

Jack may be a hand operated hydraulic jack of conventional design havinga pump handle 78 for lifting, and a release valve operable by a sternand knob 79 for lowering.

The manner of making and assembling this hydraulic body transfer hoistwill be obvious to those skilled in the art from the drawings andforegoing description. Similarly, it is thought that the manner of usingthe hoist will be apparent. By moving lever 37 the horizontal legs maybe adjusted to the required amount of spread so as to enable theoperator to fit the base under a body rest, with chains 53 centered overthe body to be transferred. Body support means 30 is strapped to thebody and hooked to appropriate links of chains 53, the height of hookingonto the chains being chosen so as to make best use of the availablelift range of the hoist. The hydraulic jack is then operated to lift thebody clear of the body rest which has been supporting it. The entirebody transfer hoist is then pushed on its casters into position with thebody above the new resting place, the lever 37 being operated as may benecessary to avoid obstructions under the new resting place. Thehydraulic jack is then lowered, lowering the body onto the new restingplace.

An important feature of my invention lies in the method of mounting thespreadable legs pivotally at the extreme rear corners of the hoist, asat 24 and 25. This permits the maximum spread of legs 22 and 23 whilestill keeping their supporting ends safely in front of or beyond theouter or front end 5252 of boom 50, as best seen at 81 and 82 in Figure3. Pivoting the spreadable legs at the rear corners of the hoist alsomakes possible the convenient and novel leg spreading mechanism.

This body transfer hoist has been found to be strong, efficient, andeasy to operate. It can be manufactured at substantially less cost thansimilar hoists riow entire market. It has a lift of about 30 inches, butlonger chains than those indicated in thedrawings permit a liftfrom anyheight.
